The Global Happiness Megastudy is a large-scale, cross-cultural, collaborative project comparing the effectiveness of eight popular, easily implemented happiness intervention strategies. Specifically, we will focus on short (<25 minute) activities that are scalable, cheap, and easily self-administered. To maximize generalizability, we intend to collect data from participants across the globe, while measuring a wide range of potential moderating factors and testing the impact of several versions of each happiness strategy. To achieve these goals, we will need a diverse team of collaborators to assist with intervention design and data collection.
